My Sugar Daddy Fucked My Girlfriend...And I Joined In

I then shoved my cock into her hole and started fucking her. I was fucking her ass, my dick going in and out rhythmically getting deeper each time, my Daddy was just on the other side fucking her vag, and I wondered if our cocks would meet in the middle of her or if we would puncture anything in her this way? We thrusted in unison: when my Daddy thrusted in, I would go out. When I went in, he'd go out. And so on. After a few minutes of this, we both came inside her at the same time.
We both stood there for a minute after we came, letting all the cum drip into her while we rested and caught our breath. "I know it's been a while since you've had pussy," my Daddy said. "So here." He removed his cock from her vag and like uncorking a campaigner bottle or blowing up a dam, liquid, probably mostly semen along with some vaginal juices, flooded out. "Go for it."
I walked over and was surprised that my cock was hard again and so quickly. Usually I could only cum once, maybe twice a night, but this night I was hard and able to cum more times than I could count! I stood in front of my naked girlfriend, who was still frozen in ecstasy, her eyes rolled up in to the back of her head, looking as if she was in another world, most probably Heaven. I doubt she knew what was going on, she could only feel it. I hesitated. "Jesus, son, I know it's been a while, but fuck!" my Daddy scoffed. "Just put your dick in her hole like you do to me." I inserted my penis into her vagina. My Daddy came up behind me and put one hand on each of my outer thighs. "Now move your legs and thrust your hips like this, like when you fuck me," he said, guiding me as if I was a baseball player in training up at bat or as if I was playing golf for the first time. As soon as I started thrusting my dick into my girlfriend I felt a sharp and sudden pain and puncture feeling in my rectum: my Daddy had decided that while I was fucking my girlfriend's vagina, he would fuck my ass. Again we thrusted in unison: he went into my asshole, I went into my girlfriend's vag. He came out of me, I came out of her. In, out, in, out...
